Greenscreen Hit Effects
=======================

12 terminal impact and effect sprites for dark interfaces — terminal black
with phosphor green accents. SVG plus transparent PNG at 1x, 2x and 4x.

Greenscreen Hit Effects is a set of 12 impact and effect sprites drawn in the
terminal style, where one hue at six levels and nothing else — a phosphor tube
has no second colour. It contains a hit spark and a critical burst, an impact
ring and a ground shockwave, a slash arc, a glow orb and a sparkle, a heal
mark and a shield bubble and a dust puff, a lightning bolt and rising embers.

Every other kit in this catalogue draws the interface. None of them draw the
moment one thing hits another, which is the first thing a combat system needs
and the last thing a solo developer gets to. An effect sprite also has no
outline to hide behind: it lives on top of the game for a few frames and then
it is gone.

The whole set is built from a single hue, including the trace and the marks,
because a phosphor or amber CRT physically cannot show a second one. The halo
is a stack of strokes at falling opacity, which is what the bloom on a real
tube looks like and what a blur filter gets wrong at 4x.

Inside that style this is the Greenscreen reading of it: a dark interface on a
terminal black palette with phosphor green accents, built around a single
bordered frame, chamfered buttons at 164x38, hollow-cored bars divided into 18
segments, and two-tone icons on a 24px grid. Those measurements are why two
families can share an art style without being interchangeable: the style
decides how an edge is drawn, the numbers decide what the interface is for.

Every sprite is centred in a square canvas and symmetric about that centre, so
the engine only has to scale and fade — an effect anchored off-centre drifts
sideways as it grows, and that reads as a bug rather than a burst. The bodies
are single-colour with no outline, because an outlined spark reads as a piece
of interface rather than as light. The glow orb is built from stacked discs at
falling opacity rather than a blur filter: a filter is rasterised differently
across engines and turns to mush at 4x.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x,
so you can drop the PNGs straight into an engine or open the vector and change
a colour. Built to the same measurements as the rest of the Greenscreen
family, which means this kit and the Greenscreen panel kit line up without
either being resized. A good fit for terminals, consoles and retro-computing
interfaces.

HOW TO USE

  - Anchor every effect at the centre of its sprite and scale from there;
    these are drawn symmetric so that scale and fade is the whole animation.
  - Play the hit spark for two or three frames at most. An impact that lingers
    stops reading as an impact.
  - Tint by multiplying rather than replacing the colour — the sprites carry
    their own light-to-dark falloff, and a flat colour replace throws it away.
  - Use additive blending for the spark, burst, glow and sparkle, and normal
    blending for the dust puff and embers, which are matter rather than light.
